LibHID is a user-space HID access library written in C. It provides a
generic and flexible way to access and interact with USB HID devices,
much like libusb does for plain USB devices. It is based on libusb, thus
it requires no HID support in the kernel. Furthermore, it aims to
support all operating system supported by libusb: Linux, BSD, OS X, and
Windows.

Force numerous ports that fail to build with clang over to instead always
rely on gcc. The patch uses the new USE_GCC=any code in Mk/bsd.gcc.mk to
accomplish this.
The ports chosen were ports that blocked 2 or more ports from building with
clang. (There are several hundred other ports that still fail to build with
clang, even with this patch. This is merely one step along the way.)
Those interested in fixing these ports with clang, and have clang as their
default compiler, can simply set FORCE_BASE_CC_FOR_TESTING=yes.
For those who have gcc as their default compiler, this change is believed
to cause no change.

Tested with: multiple runs on amd64-8-exp-bcm and 9-exp-clang, with various
combinations of patch/no-patch and flag settings.

[patch] Have devel/libhid also install its python site-package
When devel/swig13 is installed, building of devel/libhid
fails, due to my overlooking of the swig detection bits in
the ports configure script. However, swig is used to build
the python site-package of the port, so I've bumped the
portrevision and turned these bits on by default (the
additional patch-Makefile.in hunk is to suppress a warning).
